How to germinate seeds

We all know that cannabis seeds can be expensive so you don’t want to waste them with bad germination methods.

Germination also referred to as ’’popping’’, is the process in which a new plant begins to grow from a seed. Done properly, this step guarantees the healthy development of a plant. During this process, it is essential to take into consideration the seed’s needs as germination can be an intimidating stage for the new growers. This post will fully describe and uncover how to germinate cannabis seeds, as well as how to perfect the conditions for young seedlings. Let’s get into it.

General information about germination

The cannabis seed houses the whole plant and contains a reservoir of food that will turn into sugars, which the seed will use to grow. At this stage, the seed will increase in size and break open upon receiving enough moisture. This will cause the root to push through the opening and the stem will begin to consistently grow in the opposite direction to the root. Cannabis seeds necessitate three things: water, heat and air.

The most common and simplest method for germination is the wet paper towel method.

Step 1: The setup to germinate cannabis seeds

Requirements: 2 clean plates, paper towels and seeds.

Soak 4 sheets of paper towels with distilled water. Place 2 of the paper towels on the plate, place the seeds at least an inch apart from each other and cover them with the remaining sheets. Cover the plate with another plate to create a dark protected space. The area the seeds are kept in should be warm (21ºC). All you have to do after these steps is to wait.

Check the paper towels every day to ensure they’re still saturated. It is crucial that this area remains sterile and the seeds or roots (once they begin to split) shouldn’t be touched.

Most seeds will germinate within a 24-48 hour time frame. But, some seeds can take up to seven or 10 days.

Step 2: Uprooting germinated cannabis seeds

When the taproots pop from the seed, you should transplant it to its growing medium. You will need small two-inch pots filled with loose, airy potting soil. Poke a hole in the middle, about a quarter-inch down using a pen or pencil. Pay close attention when it comes to transferring the seed as you don’t want to break the root. Pick it up gently with a pair of tweezers and drop it in the hole with the taproot facing down. Cover it all with soil.

Water the soil using a spray bottle, but be careful, over-saturating the soil can kill the sprout. Always keep in check the temperature and the moisture level of the soil.

After 24 to 72 hours from being planted, a seedling will emerge from the growing medium.

Step 3: The seedling stage

The first few weeks are critical for a young marijuana plant as seeds from some of the most potent strains can be a bit delicate. From the time they emerge, new seedlings should be exposed to bright light.

Seedlings meant for outdoors should be adapted to direct sunlight and their exposure should be increased by an hour or two each day.

Seedlings meant for indoors may emerge into an artificially lit environment. For HID lighting, keep the seedlings 50-80 cm from the bulb. For fluorescent lights, a normal distance from the tube or bulb is advised.

Don’t overfill the soil with nutrients or water.

If your plant has grown a few sets of leaves, you can transfer it to a stronger potting mix with a higher level of nutrients.
